Although the creation of tests takes time, it is often a good investment as it saves time in the long run. This is because the construction of tests encourages the developer to think about the code and how it should behave in different cases. This can prevent errors from being introduced into the code and can help to locate and isolate bugs in the code. It also allows the developer to make changes to improve the code with confidence that they haven't broken anything. These benefits become larger as the code becomes more complex and the number of developers working on the code increases. For these reasons, almost all professional software development includes the development of tests.
